%X The application of magnesium (Mg) shows a curved correlativity with the fertilizer-used efficiency of N,P and K.The moderate application of Mg is very conspicuously promotive of maize absorption to N,P,and K.The application of MgO (66.7 kg/hm2) in this test,of which the fertilizer utilization coefficient of N,P,and K increases 27.61%,18.03% and 118.73% respectively than that of the comparison and the yield increases by 6.19%,enhances the contents of protein,lysine and starch being 3.40%,7.14%,and 17.15% respectively and reduces the contents of fat and sugar being 2.59% and 10.86% respectively.Over fertilizing Mg has a tendency to inhibit the accumulation of N,P,and K in plant and it is no good for yield.
